API Integration Security

🔗 API Optimization Techniques

Caching Strategies

Learn how to implement HTTP caching headers and service workers for API performance optimization. 


// Example Service Worker Caching
self.addEventListener('fetch', (event) => {
  event.respondWith(
    caches.match(event.request)
      .then((response) => {
        return response || fetch(event.request);
      })
  );
});

Response Compression

Enable Brotli compression for API responses to reduce payload size and improve load times. 


// Example Nginx Configuration
gzip on;
gzip_types application/json;
gzip_comp_level 6;
brotli on;

🔐 Advanced Security Practices

OAuth2 Implementation

Implement secure authentication using OAuth 2.0 with PKCE for client applications. 


// PKCE Code Verifier Generation
const crypto = require('crypto');
const generateCodeVerifier = () => {
  let array = new Uint8Array(32);
  window.crypto.getRandomValues(array);
  return Array.from(array, byte => 
    byte.toString(16).padStart(2, '0')).join('');
};

CORS Configuration

Configure strict CORS policies to prevent cross-origin attacks while maintaining API access. 


// Express.js CORS Setup
app.use(cors({
  origin: 'https://yourdomain.com',
  methods: ['GET', 'POST', 'PUT'],
  credentials: true,
  allowedHeaders: ['Content-Type', 'Authorization']
}));

🔧 Debugging and Monitoring

API Debugging with Postman

Use Postman's monitoring features to create automated API health checks and performance benchmarks. 


// Example Postman Test Script
pm.test("Status code is 200", function () {
    pm.response.to.have.status(200);
});

pm.test("Response has data", function () {
    pm.expect(pm.response.json().data).to.exist;
});
